解决PySide+Python子线程更新UI线程的问题

def newThread(self):
 d = Data()
 print '子线程的运行'
t1 = threading.Thread(target=newThread)
t1.setDaemon(True)
t1.start()

class Data(PySide.QtCore.QObject): 
 #定义信号
 mySignal = Signal()

 def __init__(self): 
  #这句话很重要
  super(Data, self).__init__()
 def run(self):
  mySignal.emit()

QtCore.QObject.connect(Data的实例,QtCore.SIGNAL('mySignal()'),'主线程的方法')
